The Silmarillion
At that time Beren and Luthien yet dwelt in Tol Galen, the Green Isle, in the River Adurant, southernmost of the streams that falling from Ered Lindon flowed down to join with Gelion; and their son Dior Eluchil had to wife Nimloth, kinswoman of Celeborn, prince of Doriath, who was wedded to the Lady Galadriel. The sons of Dior and Nimloth were Elured and Elurin; and a daughter also was born to them, and she was named Elwing, which is Star-spray, for she was born on a night of stars, whose light glittered in the spray of the waterfall of Lanthir Lamath beside her father's house.
Now word went swiftly among the Elves of Ossiriand that a great host of Dwarves bearing gear of war had come down out of the mountains and passed over Gelion at the Ford of Stones. These tidings came soon to Beren and Luthien; and in that time also a messenger came to them out of Doriath telling of what had befallen there. Then Beren arose and left Tol Galen, and summoning to him Dior his son they went north to the River Ascar; and with them went many of the Green-elves of Ossiriand.
Thus it came to.pass that when the Dwarves of Nogrod, returning from Menegroth with diminished host, came again to Sarn Athrad, they were assailed by unseen enemies; for as they climbed up Gelion's banks burdened with the spoils of Doriath, suddenly all the woods were filled with the sound of elven-horns, and shafts sped upon them from every side. There very many of the Dwarves were slain in the first onset; but some escaping from the ambush held together, and fled eastwards towards the mountains. And as they climbed the long slopes beneath Mount Dolmed there came forth the Shepherds of the Trees, and they drove the Dwarves into the shadowy woods of Ered Lindon: whence, it is said, came never one to climb the high passes that led to their homes.
In that battle by Sarn Athrad Beren fought his last fight, and himself slew the Lord of Nogrod, and wrested from him the Necklace of the Dwarves; but he dying laid his curse upon all the treasure. Then Beren gazed in wonder on the selfsame jewel of Feanor that he had cut from Morgoth's iron crown, now shining set amid gold and gems by the cunning of the Dwarves; and he washed it clean of blood in the waters of the river. And when all was finished the treasure of Doriath was drowned in the River Ascar, and from that time the river was named anew, Rathloriel, the Goldenbed; but Beren took the Nauglamir and returned to Tol Galen. Little did it ease the grief of Luthien to learn that the Lord of Nogrod was slain and many Dwarves beside; but it is said and sung that Luthien wearing that necklace and that immortal jewel was the vision of greatest beauty and glory that has ever been outside the realm of Valinor; and for a little while the Land of the Dead that Live became like a vision of the land of the Valar, and no place has been since so fair, so fruitful, or so filled with light.
Now Dior Thingol's heir bade farewell to Beren and Luthien, and departing from Lanthir Lamath with Nimloth his wife he came to Menegroth, and abode there; and with them went their young sons Elured and Elurin, and Elwing their daughter. Then the Sindar received them with joy, and they arose from the darkness of their grief for fallen kin and King and for the departure of Melian; and Dior Eluchil set himself to raise anew the glory of the kingdom of Doriath.
There came a night of autumn, and when it grew late, one came and smote upon the doors of Menegroth, demanding admittance to the King. He was a lord of the Green-elves hastening from Ossiriand, and the door-wards brought him to where Dior sat alone in his chamber; and there in silence he gave to the King a coffer, and took his leave. But in that coffer lay the Necklace of the Dwarves, wherein was set the Silmaril; and Dior looking upon it knew it for a sign that Beren Erchamion and Luthien Tinuviel had died indeed, and gone where go the race of Men to a fate beyond the world.
Long did Dior gaze upon the Silmaril, which his father and mother had brought beyond hope out of the terror of Morgoth; and his grief was great that death had come upon them so soon. But the wise have said that the Silmaril hastened their end; for the flame of the beauty of Luthien as she wore it was too bright for mortal lands.
Then Dior arose, and about his neck he clasped the Nauglamir; and now he appeared as the fairest of all the children of the world, of threefold race: of the Edain, and of the Eldar, and of the Maiar of the Blessed Realm.
But now the rumour ran among the scattered Elves of Beleriand that Dior Thingol's heir wore the Nauglamir, and they said: 'A Silmaril of Feanor burns again in the woods of Doriath'; and the oath of the sons of Feanor was waked again from sleep. For while Luthien wore the Necklace of the Dwarves no Elf would dare to assail her; but now hearing of the renewal of Doriath and of Dior's pride the seven gathered again from wandering, and they sent to him to claim their own.
But Dior returned no answer to the sons of Feanor; and Celegorm stirred up his brothers to prepare an assault upon Doriath. They came at unawares in the middle of winter, and fought with Dior in the Thousand Caves; and so befell the second slaying of Elf by Elf. There fell Celegorm by Dior's hand, and there fell Curufin, and dark Caranthir; but Dior was slain also, and Nimloth his wife, and the cruel servants of Celegorm seized his young sons and left them to starve in the forest. Of this Maedhros indeed repented, and sought for them long in the woods of Doriath; but his search was unavailing, and of the fate of Elured and Elurin no tale tells.
Thus Doriath was destroyed, and never rose again.
But the sons of Feanor gained not what they sought; for a remnant of the people fled before them, and with them was Elwing Dior's daughter, and they escaped, and bearing with them the Silmaril they came in time to the mouths of the River Sirion by the sea.
Chapter 23
Of Tuor and the Fall of Gondolin It has been told that Huor the brother of Hurin was slain in the Battle of Unnumbered Tears; and in the winter of that year Rian his wife bore a child in the wilds of Mithrim, and he was named Tuor, and was taken to foster by Annael of the Grey-elves, who yet lived in those hills. Now when Tuor was sixteen years old the Elves were minded to leave the caves of Androth where they dwelt, and to make their way secretly to the Havens of Sirion in the distant south; but they were assailed by Orcs and Easterlings before they made good their escape, and Tuor was taken captive and enslaved by Lorgan, chief of the Easterlings of Hithlum. For three years he endured that thraldom, but at the end of that time he escaped; and returning to the caves of Androth he dwelt there alone, and did such great hurt to the Easterlings that Lorgan set a price upon his head.
But when Tuor had lived thus in solitude as an outlaw for four years, Ulmo set it in his heart to depart from the land of his fathers, for he had chosen Tuor as the instrument of his designs; and leaving once more the caves of Androth he went westwards across Dor-lomin, and found Annon-in-Gelydh, the Gate of the Noldor, which the people of Turgon built when they dwelt in Nevrast long years before. Thence a dark tunnel led beneath the mountains, and issued into Cirith Ninniach, the Rainbow Cleft, through which a turbulent water ran towards the western sea. Thus it was that Tuor's flight from Hithlum was marked by neither Man nor Orc, and no knowledge of it came to the ears of Morgoth.
